    Note: The complete sequence may include tag sequence, target protein sequence, linker sequence and extra sequence that is translated with the protein sequence for the purpose(s) of secretion, stability, solubility, etc.
    If the exact amino acid sequence of this recombinant protein is critical to your application, please explicitly request the full and complete sequence of this protein before ordering.
  • 蛋白標(biāo)簽：
    N-terminal 10xHis-SUMO-tagged and C-terminal Myc-tagged
  • 產(chǎn)品提供形式：
    Liquid or Lyophilized powder
    Note: We will preferentially ship the format that we have in stock, however, if you have any special requirement for the format, please remark your requirement when placing the order, we will prepare according to your demand.
  • 緩沖液：
    If the delivery form is liquid, the default storage buffer is Tris/PBS-based buffer, 5%-50% glycerol.
    Note: If you have any special requirement for the glycerol content, please remark when you place the order.
    If the delivery form is lyophilized powder, the buffer before lyophilization is Tris/PBS-based buffer, 6% Trehalose.

    Store at -20°C/-80°C upon receipt, aliquoting is necessary for mutiple use. Avoid repeated freeze-thaw cycles.
  • 保質(zhì)期：
    The shelf life is related to many factors, storage state, buffer ingredients, storage temperature and the stability of the protein itself.
    Generally, the shelf life of liquid form is 6 months at -20°C/-80°C. The shelf life of lyophilized form is 12 months at -20°C/-80°C.
  • 貨期：
    3-7 business days
  • 注意事項(xiàng)：
    Repeated freezing and thawing is not recommended. Store working aliquots at 4°C for up to one week.
  • 產(chǎn)品描述：

    Recombinant Shigella flexneri Invasin Ipad with an N-terminal 10xHis-SUMO-tag and a C-terminal Myc-tag is a full-length of protein expressed in E.coli. The sequence used to prepare this recombinant Ipad protein corresponds to residues Met1-Phe332 of Shigella flexneri Ipad. Its purity is greater than 90% determined by SDS-PAGE. A molecular mass band of approximately 50-62 kDa was visualized on the gel under reducing conditions. In-stock Ipad proteins are offered. This recombinant Ipad protein may be used to produce antibodies against Ipad or in the studies of Ipad-related microbiology.

    Invasion plasmid antigen D (Ipad) is a structural component that forms a complex at the tip of the Shigella type III secretion system (T3SS) apparatus needle. It is one of the predominant virulence factors of Shigella flexneri. Olivia Arizmendi etc. demonstrated that Ipad triggers apoptosis in macrophages through activation of host caspases accompanied by mitochondrial disruption during Shigella flexneri infection. And the N-terminal domain of the Ipad is necessary for macrophage killing.

靶點(diǎn)詳情

  • 功能：
    Required for bacterial invasion of host cells. Controls IpaB and IpaC secretion, and the efficiency with which they are physically inserted into target cell membranes. These proteins are exported via TTSS to form a pore in the host membrane that allows the translocation of the other effectors into the host cytoplasm. Along with IpaB, is essential for both blocking secretion through the Mxi/Spa translocon in the absence of a secretion-inducing signal, and for controlling the level of secretion in the presence of this signal.
  • 基因功能參考文獻(xiàn)：

    2. IpaD forms part of the structure at the needle tip in Shigella flexner and antibodiesblock entry of bacteria into epithelial cells. PMID: 17110044
  • 亞細(xì)胞定位：
    Secreted. Note=Secreted via the type III secretion system (TTSS). Localizes to the tip of the external secretion needle that is part of the TTSS apparatus.
